I took an old medium format film camera with me to Paris this December and carried it for several of the days I was wandering about. While shooting with it was a much different experience than carrying a DSLR, it wasn't until the film was processed that the difference also showed greatly in the results.
The look and feel of the images, mostly on Ilford Delta 100 B&W film, harken back to the feel we'd expect of archival images from the 20s and 30s.
Update: Jan 21, 2017
A couple of the rolls of film I had sent off for processing had to be sent to a company called Boréalis in Montreal and were recently completed. These were Kodak Ektachrome 100 and required E6 processing. One roll was over mostly over-exposed, but this image, from my final day in Paris, turned out nicely. I had to wait about 10 minutes for a break in the traffic (cars & pedestrians). The people around me were quite polite, patient and accommodating while I was trying to get this shot.
